Specication of Letters Patent.

Application led May 21, 1912.

Patented J une 24, 1913. serial No. 698,695.

To all whom 1' t may concern.' A

Be it known that I, ALBERT DADE, a citizen of the United States, residing at Frankfort, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Coolers for Liquid-Dispensing Apparatus; and I do hereby declare the following to be a full, clear,l and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to li uid dispensing apparatus, and it more particularly relates to apparatus for dispensing beverages.

An object of the invention is to provide an improved cooler for beverage dispensing 'aplparatus ada ted to be secured onto a beer reg or barre for drawing beer therefrom.

A still further object of the invention is to provide a device of this character which may be quickly and easily knocked down and set u and thereby made especially adaptable dr'lispensing beverages at picnies and the like.

Other objects and advantages may be recited hereinafter and in the claims.

In the accompanying drawings, which form a part of this application, Figure 1 is a vertical sectional View through a beer keg and through an ice receiver, and having my improved beer pump applied thereto.

Fig. 2 is a vertical sectional view through the force pump element and through a two- -way connection associated therewith, and,

Fig. 3 is a vertical sectional view through the. primary liquid vduct and its adjuncts..

Referring.. to these drawings, in which similar reference characters correspond with .simila`- parts throughout the several views,

the numeral 5 designates a keg which is partly filled with liquid andhavmg afbung ole 6 in its top. A downwardly tapered' plug 7, provided with a vertical aperture 8, is seated in the bung hole. A vertical pipe 9, which will hereinafter be known as the primary liquid duct, extends through the aperture 8, having its lower end adjacent' to the bottom of the keg and its upper end secured to a pipe coil 10, through the medium of a pipe union 11, a similar union 12 connecting the coil to a pipe section 13, .which will hereinafter be known as thel exit pipe; said exit pipe being removably secured.

[to a two-way connection 14. An air pressure pump 15 is screw threaded at lt and thereby adapted to be quickly and easily connected through and member 19 and an apertured cap 20, the

with the pump pipe 13.

apertures 21 thereof being adapted to allow free access of air into the pump, an aperture 22 being provided in the hollow allowing the passage of air through the plunger, and hence through thepump. The base 19 is centrally aper-tured at 23, and this aperture is in communication with an air passage 21, which communicates with an. air pipe 25, the latter being removably secured at 26 to a member 14.

The lower end of the pipe 25 is vconnected by a union 27 to a nipple 28, the latter being connected atl 29 to the plug 7 and communieating with the primary liquid duct 9, through an opening 30 in saidliquid duct and through a valve member 31. This valve member is of rubber and is seated in a peripheral groove 32 adjacent to an end of the nipple 28, said valve member extending over and beyond said end of the nipple and into the opening 30. The valve member has a substantiall y hemispherical portion provided with a slit 33 which is normally closed. The plug 7 is provided with a screw-threaded aperture 34 having an annular shoulder 35 near its bottom, and having a rubber re taining-ring 36 fitted under the shoulder, and thereby prevented from accidental dislodgment. A screw-threaded plug 37 is fitted within the aperture 34 and bears upon the retaining ring, so as to spread the same and cause it to clamp the duct 9, for holding it in adjusted position. A faucet 38 communicates with the member 14, the opening of said faucet communicating with a liquid passage 39, the latter communicating The duct 9 is provided With an opening 40 near its lower end, so that air from the pump 15 may be forced through vthe passage24, pipe 25, nipple 28, valve member 31 and duct 9, said air entering the keg through the opening 40, and rising through the liquid tothe surface thereof and exertinga pressure thereon, the faucet 38 being closed. lWhen the faucet is open, after suiicientpressure has been obtained,` on the liquid, the latter is thereby forced through the aperture 40 and up throughthe duct 9 whence it passes through plunger for the coil 10, exit pipe 13, passage 39 and faucet 38. However., if the faucet is closed, the lpressure is maintained upon the liquid,

' so that the latter will be forced through the faucet as soon as it is open.

The valve 3l operates to prevent air from` returning upward through the pipe 25, but allows beer to pass therethrough into the pipe 9 through the slit 33 which is opened by'v the-pressure 'of air from the nipple 28, but the pressure of air or liquid on the exterior surface of the valve member-31 operates to" close the slit 33 more tightly. It will be seen that by unscrewing the nipple 28, the valve 31 may be easily replaced by another, when necessary, and it will further be seen that when the plug 37 'is loosened, the relafter be secured inplace, as shown.

In order that I may provide for "cooling the liquid while being pumped, I inclose the pipe coil 10 within an ice `receiver 4l, which is in the shape of a bottomless bowl,

and has a downwardly and outwardly eX- f tending peripheral flange 42 a short distance from its lower edge, thereby providing an annular groove 43 between said lower edge and peripheral flange 42. An annular packing ring 44, preferablyof rubber, is seated in the groove 43, and is adapted to fit snugly upon the chine 45 of the keg 5. lA bracket 46 is secured to the receiver 4l, and has the link 47 pivoted thereto, a pawl 48 being also pivoted to the bracket 46. A toothed lever 49 is pivoted to the link 47, at 50 and has the end 51 pointed and adapted to engage underthe top hoop 52 of the keg. lThe lever 49 is also provided with a handle 53; and it is obvious that by placing the ends 51 under the hoop 52 and bearing downward on the handle 53, the packing ring 44 'will be drawn down tightly on said chine so as to make a water-tight joint. The pawls 48, being in engagement with the teeth of the lever 49, hold said lever into adjusted position, as shown. The receiver 4l may now be filled with ice, the same being packed inand around thecoil l0, for cooling the liquid as it flows through the coil. llt is seen that adjustable" support noeaeee the ice will rest directly `on the head 5 of the keg, and thereby absorb a considerable amount of heat from the keg and its con tents.

ln order thatthe coil 10.-.1may be properly supported within the receiver, l provide an 54 having a base 55 resting upon the head 5 and having the cross bar 56 extending under the coil l0 and supporting the same, a standard 57 extends upward from the base 55, while a slotted arm 58 depends from the cross bar 56, and a screw or bolt 59 extends through the slot 60 and is'threaded into the standard 57, and therebyadapted to secure the coil-support into adjusted position.

The pumping mechanism may be rendered more rigid by means of the prop 61 which may be secured to the pump mechanism and to the receiver 41, by any proper means.

It will be seen that I have provided a device of this character which :is-fully .capable of attaining the foregoing objects and in a thoroughly practical and efficient manner.

I do not limit my invention to the exact details of construction, combination and arrangement of parts as herewith illustrated and described, but my invention may only be limited by a reasonable interpretation of the claims.

1. In a liquid cooling apparatus, the combinaton with a hoop-bound liquid container having 'a head, of a bottomless ice'reoeiver seated-upon the container and having means associated therewith for engaging one of the hoops and clamping it tightly to the receiver for making a liquid-tight joint, between said container and receiver.

2. In a liquid cooler, the combination with a liquid container having a head and having a chine surrounding the head of a bottomless ice receiver having an annular groove and having a packing ring fitted-in' the annular groove and adapted to be fitted upon the chine, and means for tightening the receiver upon the container, so as to make a water-tight joint between'said packing and said chine.

In testimony whereof I have signed my lname to this specification in thepresencg of two subscribing witnesses.
